Dietary Carbohydrate Consumption on Memory Performance and Mood in Children

August 7, 2017 updated by: Nick Bellissimo, Ryerson University

The Effect of Dietary Carbohydrate Consumption on Memory Performance and Mood in Normal Weight and Overweight/Obese Children

The purpose of this study is to determine the effect of carbohydrates on blood glucose levels, subjective appetite, mood, and memory performance in 9 to 14 year old normal weight (NW) and overweight or obese (OW/OB) children.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

NW and OW/OB children, 9-14 years of age, will participate in the experiment. The effect of 5 different meals (mashed potatoes, hash browns, French fries, rice, or beans matched by 50g of available carbohydrate) and meal skipping will be examined. On six separate mornings, one of the meals or no meal will be provided in a random order upon their arrival. Blood glucose, subjective appetite, and mood will be measured at baseline, 10, 30, 60, 120, and 180 minutes after meal consumption. Cognitive performance will be measured using an immediate and delayed word recall test, and two to three executive function tasks at 10, 30, 60, 120, and 180 minutes after meal consumption.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Cognitive performance
Time Frame: 10, 30, 60, 120, 180 minutes after meal consumption
Participants will participate in a battery of tests that include two learning and memory tasks and two attention tasks at 10, 30, 60, 120, and 180 minutes after meal consumption.
10, 30, 60, 120, 180 minutes after meal consumption

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Blood glucose response
Time Frame: Baseline, 10, 30, 60, 120, and 180 minutes after meal consumption
Blood will be collected at baseline, 10, 30, 60, 120, and 180 minutes after meal consumption to observe glycemic responses to 50g available carbohydrates from mashed potatoes, potato pancakes, French fries, rice, or beans
Baseline, 10, 30, 60, 120, and 180 minutes after meal consumption
Subjective Appetite and Mood
Time Frame: Baseline, 10, 30, 60, 120, and 180 minutes after meal consumption
Participants will complete subjective ratings on appetite (e.g., desire to eat, hunger, fullness) and mood (e.g. anger, happiness, excitement, sleepiness) at baseline, 10, 30, 60, 120, and 180 minutes after meal consumption.
Baseline, 10, 30, 60, 120, and 180 minutes after meal consumption
